Most viruses that spill over into new species burn out, but some persist. 🦠 A Penn State study led by David Kennedy and Clara Shaw found that infection prevalence and viral shedding were strong predictors, while severity and intensity were not. science.psu.edu/news/what-tr...

New work from the RasgonLab! Bacterial and fungal microbiomes are spatially structured across Culex tarsalis populations! www.biorxiv.org/content/10.1...

Powassan virus is a scary emerging tick-borne virus that causes neurological disease. It is great to see that my @ciddpsu.bsky.social colleagues are on top of it. www.psu.edu/news/researc...

Exciting new work from my @ciddpsu.bsky.social colleagues showing that pandemic H1N1 immunity reduces susceptibility to H5N1 infection and disease in ferrets.

Coverage of great work by my grad student @deepit.bsky.social on a new method to estimate subnational measles vaccination coverage for years without DHS surveys ... little did we know when we started that would be all years going forward.

Research, led by scientists at Penn State and the University of Pittsburgh, indicates that immunity to a seasonal influenza virus that began circulating in 2009 provides protection from severe illness from H5N1 — the strain causing the current bird flu outbreak — in a laboratory animal model.

Knowing how many people are vaccinated against an existing or re-emerging threat is a key factor guiding public health decisions, but such information is often sparse or non-existent in many regions, according to CIDD researchers @theferrarilab.bsky.social and Deepit Bhatia.

This whole thing is good. But if you need a quick pick-me up, zoom ahead to minute 42 and enjoy the soundtrack they picked for @vectorgen.bsky.social 's walk-on. It has dramatically improved my day.

It was fantastic to unplug from the chaos in the world for a few days to focus on the wonderful & impactful science being done in the Ecology & Evolution of Infectious Disease community. Huge thanks to Notre Dame for hosting @eeid2025.bsky.social and I can't wait for @eeid2026.bsky.social next year!

Thank you to the organizers of @eeid2025.bsky.social for a wonderful conference! We can’t wait for @eeid2026.bsky.social at Virginia Tech!

Thanks to everyone who came to my talk earlier today and who chatted with me after @eeid2025.bsky.social! Had many great conversations 🐄

Happy @eeid2025.bsky.social week! We’ll be sharing CIDD highlights from the week including talks, posters, and more!

New work from Abdul Wahaab in my lab! With @zureishon.bsky.social and Hieu Tran Nguyen Minh, in collaboration with ‪@joshuabenoit.bsky.social! Effect of prolonged dehydration stress on the vector competence of Aedes aegypti for Mayaro virus www.biorxiv.org/content/10.1...

I'm hiring a postdoc (Penn State Bio, CIDD @ciddpsu.bsky.social), details below. Email me if you're interested, you meet the qualifications, and you're generally a good person. Even better, if you're coming to @eeid2025.bsky.social, let's chat in real life. psu.wd1.myworkdayjobs.com/en-US/PSU_Ac...

Happening today!

#CIDDSeminar April 31, 2025, Megan Stanifer, Assistant Professor at the University of Florida College of Medicine will present key antiviral cytokines in controlling intestinal barrier formation and protection from enteric viruses.

You know, it's been a while since I posted some science. But thankfully the lab is still doing some. Here @callumarnold.bsky.social looks at the performance of epidemic early warning systems when individual case diagnostics are imperfect. arxiv.org/abs/2504.11352
